Description

Technical Field

[0001] This invention relates to the field of metal injection molding technology, and in particular to an automated metal edge cutting device for metal injection molded parts. Background Technology

[0002] Metal injection molded parts are composite structures that fuse metal and plastic together using injection molding. They are widely used in consumer electronics, medical devices, automotive parts, watch hardware, and precision connectors. During the metal injection molding process, mold design inevitably produces excess metal parts such as gates, runners, sprues, flash, or overflow. These scraps usually remain attached to the main body of the product after demolding. To obtain qualified metal injection molded parts, these scraps need to be separated from the main structure.

[0003] Chinese patent application CN202010519038.5 discloses an automatic metal scrap breaking device for injection molded mobile phone parts. The device includes a support frame with a worktable on it. The worktable has a guide rail, a pushing device, an upper breaking device, and a lower breaking device. A sliding worktable and a product placement box are mounted on the guide rail. An electrical control box is located below the guide rail. The device can slide to a receiving position via the sliding worktable to receive the injection molded part gripped by a robotic arm. The part is placed on the sliding worktable and then slid to the breaking position. The upper and lower breaking devices clamp the metal scrap portion and move it up and down, bending it multiple times to break it. The broken metal scrap falls onto the sliding worktable and is then pushed out into a discharge chute by a pushing plate. It slides down the chute into a scrap bin. The injection molded part is then sucked out by a suction nozzle and placed into the product placement box, completing the automatic breaking of the metal scrap in the plastic part. The current equipment uses a reciprocating pushing method for loading and unloading, and metal scrap is also pushed out. This requires pushing and transferring during each loading and unloading process, which wastes a lot of time and reduces the breaking efficiency of metal injection molded parts. Moreover, the injection molded parts are fixed by suction nozzles on the pressure plate, which makes them prone to falling off and unstable. Therefore, this invention discloses an automated metal scrap breaking device for metal injection molded parts to solve the above problems. Summary of the Invention

This device uses a circumferential flow method for loading and unloading injection molded parts. The loading and unloading processes are performed separately, and the metal edge trimming of the injection molded parts can be trimmed simultaneously during loading and unloading. The trimmed waste is directly discharged from the waste collection pipe, resulting in fast waste discharge. This optimizes the operation process, improves the processing efficiency of injection molded parts, and the use of a positioning module in conjunction with a pressing component enables precise positioning of the injection molded parts and ensures stable fixation of the injection molded parts during the trimming process.

[0040] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0041] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0042] Please refer to Figures 1-7 An automated metal edge trimming device for injection molded metal parts is provided, comprising a machine body 1, a feeding mechanism 2, a rotating mechanism 3, a trimming mechanism 4, and a discharging mechanism 5. The bottom of the machine body 1 is a casing 11, and a first plate 12 and a second plate 13 are fixed to the top of the casing 11. A machine cover 14 is provided on the top of the machine body 1, housing all processing steps. A human-machine interface screen 15 is fixed on the first plate 12 for operating the entire control system. The feeding mechanism 2 is located on the first plate 12 and includes a robotic arm assembly 21 and a conveyor belt assembly 22. Component 21 is positioned above conveyor belt assembly 22. The robotic arm component 21 is used to grasp the injection molded part 7 to be processed on the conveyor belt assembly 22. The feed end of the conveyor belt assembly 22 extends outside the machine cover 14 for easy placement of the injection molded part 7 in the next process. The rotating mechanism 3 is located on the first platform 12 and to one side of the feeding mechanism 2. The rotating mechanism 3 includes a turntable 31 and a fixed plate 32. The turntable 31 is driven by a power unit 35 located below the first platform 12. The fixed plate 32 is suspended on the turntable 31 and is fixedly connected to the outer shell of the power unit 35 via a vertical column penetrating the fixed plate 32. When the power unit 35 drives the turntable 31 to rotate, the fixed plate 32 remains stationary. Four circumferentially distributed positioning modules 33 are provided on the turntable 31. These positioning modules 33 are used to position and place the injection molded part 7 to be processed. Each positioning module 33 has a rectangular structure, and its top surface has a positioning groove that matches the injection molded part 7. Two pressing components 34 are provided on the fixed plate 32. These pressing components 34 are used to press down and fix the injection molded part 7 on the positioning modules 33, with the metal edge of the injection molded part 7 extending to the outside. The first platen 12, located below the pressing components 34, has a waste collection pipe 16. The robotic arm assembly 21 will then... After the injection molded part 7 is picked up by the positioning module 33, the power unit 35 drives the turntable 31 to rotate, so that the positioning module 33 on the turntable 31 rotates to the bottom of the pressing component 34. The pressing component 34 presses and fixes the injection molded part 7. The breaking mechanism 4 corresponds one-to-one with the pressing component 34. The breaking mechanism 4 breaks off the metal edge material on the injection molded part 7. Then the turntable 31 continues to rotate, rotating the processed injection molded part 7 to the next station. The unloading mechanism 5 on the second plate 13 takes the processed injection molded part 7 out of the positioning module 33, completing the automated operation of loading, breaking and unloading of the injection molded part 7.

[0043] like Figures 4-6As shown, in this embodiment, the conveyor belt assembly 22 adopts a Z-shaped structure. The inlet end 221 and the outlet end 222 of the conveyor belt assembly 22 are connected by an inclined section 223. Both the inlet end 221 and the outlet end 222 of the conveyor belt assembly 22 are planar, and the outlet end 222 is provided with a baffle plate 224. The robot arm assembly 21 is located above the outlet end 222. The injection molded part 7 produced in the previous process is placed into the inlet end 221 of the conveyor assembly. Driven by the conveyor belt assembly 22, the injection molded part 7 is moved to the outlet end 222, and the baffle plate 224 limits the position of the injection molded part 7. Furthermore, the robotic arm assembly 21 is located above the unloading end 222 of the conveyor assembly. Specifically, the robotic arm assembly 21 includes a top plate 211, which is fixed to the first plate 12 by four columns 212. A spider robotic arm 213 is installed on the top plate 211. The lower end of the spider robotic arm 213 is an adsorption and gripping end, and the range of motion of the spider robotic arm 213 covers the unloading end 222 of the conveyor belt assembly 22. At the same time, a viewing system is provided on the top plate 211. The vision system can help the spider robotic arm 213 accurately identify the injection molded part 7 on the unloading end 222.

[0044] like Figure 6 As shown, furthermore, the feed end 221 of the conveyor belt assembly 22 is also provided with a tilting assembly 23. The tilting assembly 23 includes a gantry frame 231, a tilting cylinder 232, and a tilting plate 233. The gantry frame 231 spans the conveyor belt assembly 22, and the tilting cylinder 232 is fixed on the gantry frame 231. The rotation output end of the tilting cylinder 232 is fixedly connected to one end of the tilting plate 233. The tilting plate 233 has several negative pressure suction holes. The feed end 221 of the conveyor belt assembly 22 serves as... In the feeding area of ​​injection molded part 7, when the injection molded part 7 is unloaded to the feeding end 221 in the previous process, the facing side of injection molded part 7 is not suitable for direct placement into the positioning groove on the positioning module 33. The negative pressure suction hole on the flip plate 233 adsorbs the injection molded part 7 and fixes the injection molded part 7 on the flip plate 233. The flip cylinder 232 drives the flip plate 233 to rotate in the vertical direction. Then the adsorption equipment releases the negative pressure suction hole, and the injection molded part 7 slides at an angle from the flip plate 233 to the feeding end 221, realizing the flipping of the injection molded part 7.

[0045] like Figure 4As shown, in this embodiment, a visual positioning component 6 is provided between the feeding mechanism 2 and the rotating mechanism 3. The visual positioning component 6 includes a transparent light source disk 61, and a visual camera 62 is provided below the transparent light source disk 61. The robotic arm component 21 picks up the injection molded part 7 and places it on the transparent light source disk 61. The visual camera 62 determines whether the injection molded part 7 is aligned. After the spider robotic arm 213 picks up the injection molded part 7, it first places it on the transparent light source disk 61. After the visual camera 62 below determines that the injection molded part 7 is aligned, the spider robotic arm 213 picks up the injection molded part 7 and places it on the positioning module 33. If the injection molded part 7 is not aligned, the spider robotic arm 213 adjusts the position of the injection molded part 7 according to the deviation determined by the visual camera 62 until the injection molded part 7 is aligned.

[0046] like Figure 7 As shown, in this embodiment, the diameter of the turntable 31 is larger than the diameter of the fixed plate, and the positioning module 33 is cantilevered at the outer edge of the turntable 31. The pressing component 34 includes a stand 341 fixed on the fixed plate 32. A lifting cylinder 342 is fixed on the stand 341. A lifting frame 343 is fixedly connected to the telescopic end of the lifting cylinder 342. A pressing block 344 is fixed on the lifting frame 343. The pressing block 344 matches the positioning module 33, and the planar dimensions of the pressing block 344 are consistent with the planar dimensions of the positioning module 33. After the positioning module 33 moves to the position of the pressing component 34, the lifting cylinder 342 drives the lifting frame 343 to move down, so that the pressing block 344 fits with the positioning module 33, pressing and fixing the injection molded part 7. The metal edge material on the injection molded part 7 is exposed outside the positioning module 33 and the pressing block 344, so as to facilitate the breaking mechanism 4 to break the metal edge material.

[0047] like Figures 7-9As shown, furthermore, the breaking mechanism 4 consists of two sets. Each rotation of the turntable 31 can break the metal edge material of the injection molded part 7 on the two positioning modules 33. The two sets of breaking mechanisms 4 can break the metal edge material on different sides of the injection molded part 7, or simultaneously break the metal edge material on multiple sides of the injection molded part 7. Specifically, the breaking mechanism 4 includes a horizontal slide rail 41, a horizontal slide block 42, and a horizontal cylinder 43. The horizontal cylinder 43 drives the horizontal slide block 42 to slide along the horizontal slide rail 41. A vertical slide rail 44 is fixedly connected to the horizontal slide block 42. A vertical slide block 45 is slidably connected to the vertical slide rail 44. A breaking module 46 is fixedly connected to the vertical slide block 45. A drive disk 48 driven by a drive motor 47 is provided. The drive disk 48 is connected to the vertical slide 45 by a drive rod 49. The drive rod 49 is eccentrically connected to the drive disk 48 and is also movably connected to the vertical slide 45. The transverse cylinder 43 drives the transverse slide 42 to move the vertical slide rail 44 closer to the positioning module 33 until the breaking module 46 contacts the metal edge material on the injection molded part 7. Then, the drive motor 47 drives the drive disk 48 to rotate. The drive disk 48 drives the vertical slide 45 to move up and down reciprocally through the drive rod 49, repeatedly bending the metal edge material on the injection molded part 7 until the metal edge material falls off the injection molded part 7, completing the breaking operation of the metal edge material on the injection molded part 7. In this embodiment, the breaking module 46 is L-shaped and includes a lower module 461 and an upper module 462. An L-shaped groove 463 is provided at the junction of the upper module 462 and the lower module 461. The L-shaped groove 463 allows the breaking module 46 to break the metal edge material on two adjacent sides of the injection molded part 7 each time, thereby improving the breaking efficiency.

[0048] like Figures 10-12As shown, in this embodiment, the unloading mechanism 5 includes a linear guide module 51 spanning the first platen 12 and the second platen 13. A translation seat 52 is slidably connected to the linear guide module 51, and a lifting device 53 is fixed on the translation seat 52. The lifting device 53 is driven to connect a negative pressure adsorption device 54. The negative pressure adsorption device 54 is used to adsorb and fix the injection molded part 7. The linear guide module drives the lifting device 53 to move back and forth between the first platen 12 and the second platen 13. The lifting device 53 drives the negative pressure adsorption device 54 to descend, so as to adsorb and fix the injection molded part 7 with broken metal edge material, and then transfer the injection molded part 7 to the unloading area. Furthermore, a tray-stacking assembly 55 and a linear module 56, fixed on a second platen 13, are provided in the unloading area. The tray-stacking assembly 55 includes an empty tray area 551, a tray loading area 552, and a tray-stacking area 553. Empty blister trays 8 are stacked at an angle in the empty tray area 551. The linear module 56 is equipped with a shifting frame 561. The linear module 56 drives the shifting frame to move the blister trays 8 from the empty tray area 551 to the tray loading area 552, and then moves the blister trays 8 from the tray loading area 552 to the tray-stacking area 553. The shifting frame 561 on the linear module 56 can clamp empty blister trays 8 from the bottom of the tray-stacking area 553 and then move the empty blister trays 8 to the tray loading area 553. 2. The moving direction of the movable frame on the linear module 56 is the Y-axis direction, and the moving direction of the translation seat 52 on the linear guide module 51 is the X-axis direction, so that the moving direction of the movable frame is perpendicular to the moving direction of the translation seat 52, which makes it convenient to fill the empty blister tray 8 with injection molded parts 7. Furthermore, the tray area 553 is provided with symmetrical lifting devices 554, and the two sides of the lifting devices 554 are provided with unidirectional rotating support blocks 555. The support blocks 555 can only rotate upward in one direction, and after rotation, it is convenient for the lifting devices 554 to lift the blister tray 8 and move it upward, so that the blister trays 8 containing injection molded parts 7 are stacked from bottom to top in the tray area 553.

[0049] The working principle of the automated metal scrap breaking device for metal injection molded parts provided by this invention is as follows: The robotic arm assembly 21 picks up the injection molded part 7 to be processed from the conveying assembly and places it on the positioning module 33. The turntable 31 rotates the positioning module 33, which holds the injection molded part 7, to the pressing assembly 34. The pressing assembly 34 presses and fixes the injection molded part 7. The breaking mechanism 4 breaks off the metal scrap on the injection molded part 7. The broken metal scrap is discharged through the waste collection pipe 16. The turntable 31 continues to rotate, and the unloading mechanism 5 feeds the metal scrap onto the injection molded part 7. After the injection molded part 7 is removed, the injection molded part 7 is loaded and unloaded in a circular flow manner. The loading and unloading processes are carried out separately, and the metal edge material of the injection molded part 7 can be broken off at the same time as loading and unloading. The broken waste material is directly discharged from the waste material collection pipe 16. The waste material is discharged quickly, the operation process is optimized, and the processing efficiency of the injection molded part 7 is improved. In addition, the positioning module 33 and the pressing component 34 can accurately position the injection molded part 7 and ensure the stable fixation of the injection molded part 7 during the breaking process.
